BICYCLE-STAN DING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 641,609, dated January16, 1900.

Application filed May 11,1899. Serial No. 716,428. (No model.)

To all whom it may concern.-

Be it known that I, GIIABENcE L. RYMAL, a citizen of Canada, residing atHamilton, in the county of Wentworth, in the Province of Ontario,Canada, have invented new and useful Improvements in Adjustable Bicycle-Standing Attachments, of which the following is a specification.

My invention relates to an adjustable bicycle-standin g attachment inwhich the central eye part of a coil or scroll-shaped steel-wire springis inwardly extended and secured to the outer part of the rigid axle ofthe rear drive-wheel of a bicycle, the outer end of said wire springextending far enough downward in locked position to stand the bicycle.Said extended end is capable when unlocked of rising by its inherentresiliency to a horizontal position and then brought upward to and inline with the rear-fork brace of the bicycle and locked thereto.

The objects of my invention are, first, to provide a device which may beeasily and permanently attached to a bicycle for standing the same, and,second, to afford facilities for raising the device to a locked positionthat shall in no manner interfere with the proper riding of the bicycle.I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which-- Figure 1 is a side elevation of my improvedadjustable bicycle-standing device secured in standing and lockedposition to the rigid axle of the rear wheel of an ordinary bicycle,parts of which are broken away in order not to interfere with thecomprehension of the device, and to avoid complexity the device is alsoshown in upper locked position in broken lines. Fig. 2 is an enlargedside elevation of the device in standing and locked position, the end ofthe axle, with securing nut, being shown in the central part, thebicycle being removed. Fig. 3 is an elevation of the same as viewed fromthe front, showing attachment to the axle and the rear-fork brace, bothof which are broken. Fig. 4c is a plan of the lower lock and of thestay, showing rear opening to receive the extended leg part of thescroll to lock the same in standing position; and Fig. 5 is a plan ofthe upper locking device which is secured to the rear-fork brace of thebicycle, as shown in section.

Similar letters and numerals refer to similar parts throughout theseveral views.

In the drawings the steel scroll part of this bicycle-standingattachment is indicated by A, its downwardly-extended leg by B, its lookby C, having arm 8, its lower stay by D, having arm 10, and its upperlock and support by E. The central part 2 of this device is extended atthe inner side and has an eye to fit on the rear rigid axle 4 of abicycle and against the rear-fork brace H thereof, and secured theretoby a washer J and nut K in permanent position. This central and innerextended part of the scroll A may be of single or of double formationand arranged to allow sufficient space for the not between the scrollproper and its central inward part. The inherent resiliency of thescroll-spring, when unlocked, would bring the leg B to about horizontalposition or parallel with the bicycle. Therefore when the leg ispositioned, as shown, in the rear openings 6 of the lock 0 and of thelower stay D, both of which form rigid parts thereof, the leg is firmlyheld in said openings by its own inherent resiliency, as the tendency ofthe leg is to bound forwardly upward to horizontal position, aspreviously mentioned. It will be observed that there is an upward springalso to the leg on account of the scroll formation of the upper part.This spring tendency is advantageous to the bicycle, avoiding rigidityand sudden jars.

When the leg is brought forwardly upward to the rear-fork brace H of thebicycle, it is lodged in the rear opening 14, formed in the lock E,which is bent toward the rear. This lock E is secured to said brace H inapproved manner. The said opening 14 of this look E is forwardly closed,the tendency of the leg being to press forwardly downward of its ownaccord. This inherent resiliency contained in this bicycle-standingattachment, as set forth, is the important element in the constructionthereof. It will be noticed that the openings in the said locks andlower stay are all forwardly closed, of necessity, to perform theirproper functions.

This bicycle device is shown attached to the right-hand side of abicycle. The said device may be attached to either side, the resultsbeing identical, no matter on which side of the bicyclethe device may beattached.

Variouschanges in the form, sizes, and proportions of my invention maybe resorted to without departing from the spirit and scope thereof.Hence what I claim as my invention, and desire to secure by LettersPatent, 1s-

1. An adjustable bicycle-standing attachment of the character described,consisting of a scroll or coil spring, a lower lock, alower stay and alock attached to the rear-fork brace, the central part of said springinwardly extended and formed with a central eye to fit on the rear-wheelaxle and secured thereto and. against the rear-fork brace bya washer andnut, the outer fore part of said spring extending downward with extendedfoot and secured byits own inherentresiliency against theforwardly-closed ends of the-lower lock and the lower stay forminga partof the spring, said leg capable by its own inherent resiliency oflocking in the lock attached to y the rear-fork brace of the bicycle.

the outer and rear part of said spring extended downward as a leg andsecured in the lower lock and in the lower stay, forming a part of saidspring by its own inherent resiliency against the forwardly-closedopenings in said lock and stay, said leg capable of being secured bymeans of its inherent resiliency in the lock of the rear brace.
